        Need a way to regression test .webarchive output files

        Implement layoutTestController.dumpAsWebArchive() to test WebArchive format.
        Saves WebArchive plist in xml format, then alters file:// URLs to remove path
        where WebKit was checked out.

        * DumpRenderTree/DumpRenderTree.m:
        (serializeWebArchiveToXML): Added.
        (dump):
        (+[LayoutTestController isSelectorExcludedFromWebScript:]):
        (-[LayoutTestController dumpAsWebArchive]): Added.
